Independent testing at the Quintic Ball Lab USA in Massachusetts confirmed the importance of MOI, moment of inertia, resistance to twisting. Quintic Ball Roll Lab USA in a second phase of testing explored the impact of the utilization of the extreme weight range allowed by the Cure RX Series putter. In this human (no more robots) testing we discovered the surprising benefit of weight optimization fitting.
The alpha test was with a 16 handicap golfer; an average putter for his handicap with a 2.9o face angle variation range in his baseline putter test. 9 Cure RX Series putter configurations were tested. Face angle variation range decreased (improved) in the first 5 tests; and then failed to improve more in the last 4 tests. The putters in tests 1-5 “felt” good to the player; the putters in tests 6-9 “felt” too heavy to the player. An OPTIMUM WEIGHT was discovered at 409 grams for this player.
The alpha test discovered an optimum weight outside the industry expectation (as indicated by the average weight of available putters) of between 345g and 355g. Improvement in a number of putter launch metrics was noted, including importantly: putter speed variation range, launch angle range, and zero skid range.
The beta test was with a 6 handicap golfer; a relatively poor putter for his handicap with a 2.1o face angle variation range in his baseline putter test. 9 Cure RX Series putter configurations were tested. Face angle variation range decreased (improved) in the first 2 tests; and then failed to improve more in the last 4 tests. The putters in tests 1-4 “felt” good to the player; the putters in tests 5-9 “felt” too heavy to the player. An OPTIMUM WEIGHT was discovered at 395 grams for this player.
The optimum weight for face angle variation range and putter speed variation range coincided at the same weights; with the same pattern: improvement up to the optimum weight and then no further improvement.
Subsequent tests have been done with players of all skill levels including PGA Tour players, PGA Tour Champions players, LPGA Tour players, web.com and mini Tour players, International Tour players and amateurs from +4 handicap to -32 handicap. The results persistently confirm an optimum weight for players of all skill levels a putter weight heavier than generally available in the market.
The results are GAME CHANGING!
Average players can improve their putting to tour caliber without a putting lesson. Simply put a weight optimized, MOI maximized putter in their hands and their putting launch monitor metrics improve, a lot!
This is scientific proof that each player has an optimum weight, individually determinable.
